Built-up British rifle

The Armstrong gun, designed by Sir William Armstrong, was a British rifled gun known for its built-up construction of wrought iron, coiled and welded, and for the breech-loading mechanism of many of its patterns. It fired a lead-coated projectile that took the shallow rifling.

Armstrong guns and their ammunition reached North America only in small numbers during the Civil War, and surviving Armstrong ordnance from the conflict is uncommon.
